| ✪ Ankerite ? Formula: Ca(Fe2+,Mg)(CO3)2 Habit: curved Rombohedral xtls Colour: Yellowish white, frequently with a brown superficial coating Description: Benchmark chemical analysis of samples by W.P. Headden as reported in the 1874 Second Geological Survey of Pennsylvania, by F. A. Genth. Often occuring with a brown superficial coating, frequently associated with Pyrite crystals. I.D. noted as doubtful by A. Montgomery, Min PA, 1922-69. discredited status contested by A. Heyl in USGS study 1984 (MinRec v20 #5 pg. 377)
Published analysis, in Montgomery, "Mineralogy of Pennsylvania," 1922, gives Ca(Mg0.63Fe0.37)(CO3)2, suggesting the mineral is Fe-containing dolomite. Heyl's report not examined, could be from a legitimate ankerite, however. |
